• If you are trying to use Boolean operators, they must be ALL CAPS: %22coinage %((28 law) OR (20 law)) AND legislation %((2f france) OR (20 france)) %((21 early) OR (2.1 early)) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22coinage %((28 law) or (20 law)) and legislation %((2f france) or (20 france)) %((21 early) OR (2.1 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22coinage %((28 law) or (20 law)) and legislation %((2f france) or (20 france)) %((21 early) OR (2.1 early)) works to 1800%22*.
